The Mayer-Rokitansky-Kuster-Hauser (MRKH) syndrome is comprised of vaginal atresia with other variable Mullerian duct abnormalities. Its features include an absent or very short vagina and a uterus that can be absent or immaturely formed. Female with MRKH syndrome have functioning ovaries, normal external genitalia and the typical 46, XX, karyotype. MRKH syndrome is the second most common cause of primary amenorrhea, usually remains undetected until the patient presents with primary amenorrhea despite normal sexual female development. We report a case of MRKH syndrome, associated with ovarian follicular cyst, in a 14-years-old girl who visited for primary amenorrhea and sexual precosity.

Pigmented follicular cyst is a rare disorder which typically presents as a pigmented papule on the head or neck. Histologically, it exhibits terminally differentiated, pigmented hair shafts in an epidermoid cyst. It was described as a variant of epidermal cyst originating from the infundibular epidermis of pilosebaceous unit. We report a case of pigmented follicular cyst on the occipital scalp in a 7-year-old girl with typical histologic features.

We report a pigmented follicular cyst (PFC) in a 40-year-old male manifestated clinically as pigmented nevus. Histopathologic findings revealed an infundibular cyst in the mid dermis containing a small amount of keratinous material. The cystic wall consisted of four or five layers of squamous epithelium with a granular layer with abundant keratohyaline granules and the cyst wall contained one hair follicle. It must be differentiated from other pigmented lesions of over-lying skin such as eruptive vellus hair cyst, apocrine hydrocystoma and melanocytic nevus coexistance of an epidermoid cyst. Surgical excision and histopathological examination are necessary for an accurate diagnosis in pigmented lesions.

A pigmented follicular cyst typically presents as an asymptomatic, solitary papule on head and neck in adult men. The histologic features of pigmented follicular cysts are cross-sectioned, terminally-differentiated hair shafts in an epidermal cyst. There are no sebaceous lobules or other appendages within the wall or in close proximity. We herein report a case of pigmented follicular cyst of the axilla in a 31-year-old man.

On H1 MRS (magnetic resonance spectroscopy), malignant tumors show higher concentration of metabolite than benign lesions. Lactate double peak was detected in malignant tumor and endometriosis, and more prominent high concentration was demonstrated in endometriosis. Tuboovarian abscesses and salpingitis do not show prominent peak. Dermoid cysts show high levels of lipid peak. Paratubal cyst and follicular cyst can be showed the lipid peak, however, the concentration of lipid is lower than that of dermoid cyst. H1 MRS of ovarian cystic lesions can give valuable information about the presence of metabolites of ovarian cystic lesions.

PURPOSE: The purpose of this study is to evaluate the characteristic MR findings of sacrococcygeal pilonidal sinus. MATERIALS AND METHODS: Eight MR images of pathologically proven sacrococcygeal pilonidal sinus were retrospectively reviewed [M: F = 7: 1; age range 9-41 (median, 17) years]. In all cases, a sacrococcygeal mass was present. Five of the eight patients experienced pain, and in three was discharge. MR findings were evaluated with regard to the location and extent of the lesion, and the presence of sinus or cyst, and the results were compared with the pathologic findings. RESULT: According to the clinical manifestations, each case was assigned to one of four groups: the first type (n= 3) showed dermal thickening with subcutaneous fatty infiltration of the ipsilateral natal cleft while pathologically, a follicular cyst with dermal fibrosis and multiple fatty lobules with fibrous septa were found to be present. In the second type (n = 3), fluid was observed in the sinus tract, while the pathologic findings demonstrated the presence of an abscess in this area. In the third type (n = 1), a cystic lesion with airfluid level was present; pathologically, an abscess was revealed. The fourth type (n = 1) showed only a low signal intensity sinus tract on both T1 and T2-weighted images, while the pathologic findings indicated the presence of hairs and follicles within the tract. CONCLUSION: The MR findings of sacrococcygeal pilonidal sinus depend on the clinical manifestation and include subcutaneous fatty infiltration, a sinus tract with or without fluid retention, and a cystic lesion with air fluid level. These findings could be helpful for differentiating between this and other sacrococcygeal lesions.

An eruptive vellus hair cyst is an uncommon, benign, epithelial tumor with hair differentiation. Clinically, it presents as asymptomatic, flesh-colored to yellowish, follicular papules, 1 to 4 mm in diameter, most commonly on the chest. It is usually seen in children and young adults but may be congenital. Histologically, it shows a middermal cyst lined by squamous epithelium containing keratinous material and vellus hairs. It has a tendency to clear spontaneously but may be persistent. We report a case of congenital eruptive vellus hair cyst in an 11-year-old girl who presented multiple pinhead-sized brown to black papules on her anterior chest since birth.

Sebaceous trichofolliculoma is a rare benign tumor and represents a variant of trichofolliculoma. It presents as a centrally depressed solitary tumor and occurs in areas rich in sebaceous lobules. Microscopically, it shows keratin-filled cystic cavities and sebaceous lobules. The lobules are connected to the cystic wall. Herein we report a case of sebaceous trichofolliculoma on the right cheek in a 64-year-old man.
